Application January 31, 1942, Serial No. 429,047

1 Claim. My invention relates to an improved method of sealing stamps or other articles by decalcomaniaA and has for it object to provide aseal applied of substantial value.

A particular need for an effective seal such as my invention provides arises out of stamps to be applied for public display upon the windshields of automobiles, such for example as the automobile use tax stamps, automobiley gasoline ration stamps, and the like. There are other in strumentalities which might advantageously be sealed upon a surface so that they. may be inspected, and yet by the seal will besafeguarded.

It is the principal object of my invention, therefore, to provide a method of sealing a stamp or other valuable matter which may be required to be exposed to view, which consists in applying a stamp such as an automobile use stamp upon the windshield of an automobile with its face out, and applying a decalcomania piece of suitable size which has been Wet until limp over the back of the stamp, and rolling or sliding the backing sheet off of the decalcomania surface, thereafter i smoothing and permitting it to dry.

It is a further object of my invention to form in conjunction with the decalcomania sheet certain ornamental design, including a warning that the stamp is stolen if removed from the seal.

It is a further object of my invention to have formed upon the backing of the decalcomania seal instructions as to how the same shall -be used.

The full objects and advantages of my invention will appear in the specification hereinafter given, and the novel features by which the above noted advantages are obtained will be particularly pointed out in the claims.

In the drawing, illustrating one form of means for carrying out my invention:

Fig. 1 is a plan view of a decalcomania seal employed in connection with my method.

Fig. 2 shows the back view of the decalcomania employed in my method with instructions for application printed on the backing sheet of said decalcomania.

Fig. 3 shows the back view of the decalcomania after sliding backing sheet off, and thus shows the warning concerning "stolen stamp, which appears over the reverse side of the stamp sealed under the decalcomania after the sliding off of the backing sheet.

In Fig. 1 is shown a decalcomania of rectangular shape and suitable size, having a backing sheet I, and having a space 2 to receive the stamp that is to be sealed in andvprotected, and having suitable border `ornamentation 3 4. The decalcomania transfer may be of the same size as the backing sheet, but is shown of a somewhat smaller size,.as indicated by its edge outlined at 5. v

Fig. 2 illustrates at 6 a set of directions for applying the decalcomania seal, which if followed will carry out the steps of my process.

Fig. 3` illustrates the decalcomania seal itself after it has been removed from the backing sheet carrying the warning on its face, as indicated at 1.

When the decalcomania sheet as an entirety is immersed in water the adhesive gum between the transparent transfer sheet and the backing sheet is quickly dissolved so that the backing sheet can readily be removed by sliding it from under the transfer sheet, leaving a layer of moist adhesive upon the surface ofv the' transfer sheet by which it will be made to adhere to the surface of the attach it.

I employ a standard decalcomania transfer. The decalcomania itself as used in my process is well known. My invention consists in using 30 this decalcomania transfer for the purpose of sealing ina stamp or other valuable object, specically an automobile use tax stamp.

In the practice of my invention where it is desired to seal inv a use stamp on an automobile windshield, the first step is to clean the Windshield. Then the decalcomania strip made up of the backing l and the decalcomania proper 5, is immersed in water until it becomes limp. After this the stamp is placed upon the damp glass of the windshield on the inside of the windshield with the stamp face out. Then the moistened decalcomania sheet is placed over the back of the stamp and the backing sheet is slipped out from between the back of the stamp and the decalcomania transfer after which the back of the transfer will be smoothed out and dried by a suitable cloth and it will set in place and permanently hold and protect the stamp sealed under it. And since this stamp faces outwardly, it will be readily viewed from the outside of the windshield.

The primary advantage of my invention re- '55 windshield'and the like) and which has very glass or other'material to which it is desired to substantial value is completely protected against injury or loss, and that it can be done in a very simple and inexpensive manner.

I claim:

A method of sealing a document such as an automobile use stamp upon a. surface Where it will be in an exposed position, which consists in forming a -decalcomania sheet with removable transfer `.sheet thereon, applying fthe 'stamp Hto the surface, wetting the decalcomania sheet, placing the wet decalcornania sheet over the stamp as so applied, slipping the back of the deca-lcomania sheet from the transfer sheet thereon with the stampbetween it and the surface, and smoothing and drying the transfer sheet over the stamp.
